The TS3DV421 is a 4-channel differential 2:1 multiplexer/demultiplexer digital video switch controlled with one select input (SEL). SEL controls the data path of the multiplexer/demultiplexer and can be connected to any GPIO in the system, using an external voltage divider system. The device provides high bandwidth necessary for DVI and HDMI applications. This device expands the high-speed physical link interface from a single HDMI port to two HDMI ports (A or B port). The unselected channel is set to a high-impedance state.

The most common application for the TS3DV421 is in the sink application. In this case, there are two sources (i.e., DVD, set-top box, or game console) that must be routed to one HDMI receiver. The TS3DV421 can route the signals where one HDMI receiver (in a DLP, LCD TV, PDP, or other high-definition display) can be expanded to three ports.

The HDMI application calls for a 100- differential impedance between the differential lines (TMDSn+ and TMDSn–). Additionally, because the TS3DV421 is a high-bandwidth, low-rON pass transistor-type switch, a properly designed board retains a 100- differential impedance through the switch. The unselected port is in the high-impedance mode, such that the receiver receives information from only one source. HDCP encryption is passed through the switch for the HDMI receiver to decode.
